Prov 19:17 says those gracious to the poor are lending to God. It's hard for anyone familiar with the New Testament to think about such a statement for very long without being reminded of Jesus' discussion in Matthew 25, where he says, "whatever you do to the least of these, you do to me."
It amazes me how far people will go to find sources outside the Hebrew tradition for some of Jesus' ideas. So many of his statements are steeped in the language and conceptual framework of the Hebrew scripture. The extent of these connections don't often enough get noticed, and not all of them are as obvious as others, but enough of them are transparent enough that I have to wonder if the people who make such statements know the Hebrew scriptures very well.
Christians will look at this example as a proverb in the Hebrew scriptures teaching a principle that would come to be exemplified in Jesus' teaching about himself, with the implication that Jesus is according himself divinity by taking on a feature the Hebrew scriptures reserve for God. But even those more skeptical of such notions should at least admit that Jesus' teachings are so strongly influenced by the Hebrew Bible and that it's contextually insensitive to take Jesus to be primarily something more like a Roman Stoic or an adherent to the teachings of some kind of eastern mysticism. Where there might be similarities there, his actual background, language, and cultural milieu serve as a far better explanation even of the teachings that are fairly distinctive in the gospels and not found with such close parallels such as this one.
